Know all men that I, THOMAS J. JONES, of Rochester, in the county ofOakland, and State of Michigan,

have invented a new and useful Improvement in Adjustable Neck-Yokes; andI do declare that the followingis a true and accurate descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, and being a part of thisspecification.

Figure 1 is a perspective view of my inventiou;

Figure is a sectional view of the same on the liner: x-in fig. 1.

The same letters indicate like parts in each figure.

The nature of'this invention is so to construct a neck-yoke that it willadjust itself vertically, so that it will act as a. long and short yokein one, and at the same time allow for the roll of the yoke, and workreadily in any position the yoke may assume while in use. By thisarrangemenhthe yokeis so arranged as to equalize the draught, and compeleach horse to perform his equal share of the work in holding bacl z thevehicle in descending declivities. Ialso prevent, the danger and troubleof the lines catching under any bars.

To accomplish this object I take a neck-yoke, the bar of which isconstructed in the ordinary form, and

little longer than usual when built without the attachment I am about todescribe. To this bar, A, are attached .at each end proper rings, B B,which play upon the bar within the guards QC. To these rings BB, and ontop of the bar A, are attachedthe rods D D, which, at their oppositeends, are attached to the circle E, which is, fastened to the bar A by aproper hinge, both passing through the bar A and the-centre of the banF, which forms the arms of the circle. The hinge bolt Gr allows the rodsD to work freely and readily,'no matter what the position or roll of theyoke when in use. '11 is the ring, through which the pole of the vehiclepassorigami by which it is held up. II are rings, to whichthe-breast-straps of the harness are attached, and the smaller rings, JJ,'are those through which the martingales are fastened. V i

What I claim as my invention, and desire to secure hy'Letters Patent,isy 1. The circle E and the bars D D F, when arranged substantially asand for the purpose set'forth. 2. The hinge-boltG, when constructed andoperating substantially as described. V

'3. The combination of the above-named parts with the bar'A, the rings BB, H, I I, "and J J, the guards C 0, all arranged andoperatingsnhstantially as and forthe'purposes specified.
